H&R 52998 Street Performance Coilover Kit

The H&R 52998 Street Performance Coilover Kit is a complete, vehicle-specific suspension system engineered to deliver a balanced combination of everyday ride comfort and responsive performance handling. H&R is widely recognized as the originator of the true coilover system for street use, and this kit reflects decades of suspension engineering expertise.

At the core of the system is an advanced mono-tube gas shock construction — a significant step up from conventional twin-tube shock absorbers. Each shock is custom-valved to work in direct harmony with a precision-engineered progressive rate spring, creating a cohesive, finely tuned suspension system rather than a collection of mismatched components.

Key Features:

• Innovative mono-tube gas shock design for superior damping response
• Progressive rate springs custom-matched to each shock's valving
• Fully threaded shock body for precise, adjustable ride height
• Front lowering range: 1.2" – 2.2" | Rear lowering range: 1.0" – 2.1"
• Easy-to-adjust spring seats allow height changes for seasonal or style preferences
• Complete coilover system — matched components designed to work together
• Suitable for daily drivers and performance-oriented tuners alike

The fully threaded shock body allows for repeatable, accurate ride height adjustment without compromising suspension geometry or ride quality. Whether you're looking for a modest street drop or a more aggressive stance, the H&R 52998 delivers the flexibility to dial in your ideal setup with confidence.
